[php] Error bei GIF-Erzeugung

[=?ISO-8859-1?Q?Daniel_Oberl=E4nder?=]

Hallöchen!

Wenn ich GIF-Dateien nach dem PHP Handbuch (Kapitel 15) erzeugen will,
bekomme ich vom Server immer folgende Fehlermeldungen:

/usr/local/apache/1.3.12/logs/error_log:

http://localhost/bild.php:

<?php    Header("Content-type: image/gif");
    $string=implode($argv," ");
    $im = imagecreatefromgif("bild.gif");
    $orange = ImageColorAllocate($im, 220, 210, 60);
    $px = (imagesx($im)-7.5*strlen($string))/2;
    ImageString($im,3,$px,9,$string,$orange);
    ImageGif($im);
    ImageDestroy($im);
 ?>


Die Datei 'bild.gif' existiert übrigens. Weiß irgendjemand Rat???

Gruss,
